Effect of anesthesia induction with butorphanol on postoperative nausea and vomiting: A randomized controlled trial

Table 5 Comparison of actual doses of propofol and remifentanil, agitation scores, Bruggrmann comfort scale scores, and effective compressions of patient-controlled intravenous analgesia pump

	Sufentanil group (n = 55)	Butorphanol group (n = 55)	Z	P value
Propofol (mg)	1027.2 ± 461.6	1016.4 ± 379.4	-	0.893
Remifentanil (mg)	1.3 ± 0.6	1.2 ± 0.5	-	0.438
Agitation score (0/1/2/3)	42/8/5/0	47/6/2/0	-0.774	0.439
BCS score (0/1/2/3/4)	6/5/30/14/0	1/4/24/25/1	-2.195	0.028a
Effective compressions of PCIA	1.00 (2.00-1.00)	1.00 (2.00-1.00)	-	0.881

^aThere is significant statistical difference between the two groups, with P < 0.05.

BCS: Bruggrmann comfort scale; PCIA: Patient-controlled intravenous analgesia pump.
